Here are possible candidates to lead the Cubs after the ouster of Jim Hendry:
Rick Hahn: The Chicago White Sox vice president/assistant general manager is considered one of the top GM prospects in baseball. He oversees all aspects of baseball operations, and has a keen knowledge of sabermetrics. Baseball America ranked him a the top GM prospect in 2010. He's played a role in roster composition, acquisitions, talent evaluation and contract negotiations with the White Sox.
Josh Byrnes: The former Arizona Diamondbacks GM was groomed in the Boston Red Sox organization under Theo Epstein. The Diamondbacks went 349-378 in four-plus seasons under Byrnes. Arizona reached the NLCS in 2007. Byrnes is knowledgeable in the sabermetric side of baseball, and he's also been credited with solid payroll management.
Bobby Cox: Known for his long, successful run as manager of the Atlanta Braves, Cox also served as the Braves' GM from 1985-1990. Cox won four Manager of the Year awards and one World Series championship as manager of the Braves and Blue Jays. He also won 100 or more games in six different seasons.
John Schuerholtz: The man who signed away Greg Maddux from the Cubs was the Braves GM from 1990 to 2007. He was also the GM of the Kansas City Royals from 1982-1990. He won 2 World Series championships and 15 division titles during his tenure with those two clubs.
Terry Ryan: He had the difficult task of succeeding Andy MacPhail, who built two Twins World Series champions. When MacPhail left to take over the Cubs in 1994, Ryan took over as GM and endured losing seasons until 2001. But Ryan turned the small market Twins into a winning organization by building through the farm system. Beginning in 2001, Minnesota had winning seasons in six of seven seasons until Ryan stepped aside as GM after the 2007 season.
Pat Gillick: The special adviser for the Philadelphia Phillies has said he's not interested in being a GM, but he would take a president-level position with another team. Gillick, 74, was the architect of two world championship teams with the Toronto Blue Jays in 1992 and 1993 and one with the Phillies in 2008.
